13 months in and nothing lexus-made has broken (some issues related to my modifications).
My first service did cost me £1000 though. Due to not knowing the exact details of previous services and 107k miles on the clock, I played it safe and did the spark plugs and gearbox fluid along with the routine items. Along with the tax, insurance and fuel economy it isn't cheap to run but I think it is definitely worth it 😎
